D Correct answer
Explanation

Hill soils that are present at foot hills of Aravallis are also called as lithosols. Dungarpur, Banswara & parts of Udaipur, Chittorgarh districts have such soils. These soils are reddish in colour with granular/crumb structure & well drained. These soils have rich content of iron-oxide and devoid of calcium salts because calcium salts soluble in water and are easily washed away. Soils are suitable for maize, chillies, wheat, barley and rapeseed cultivation.

  2. Rainfall

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Formation of soil is called pedogenesis. Soil formation is the process of soil formation from its parental material. In most of the cases colouration, mineral composition and texture of the soil is determined by its parental material. In addition to the soil parent material, soil formation is also dependent upon other prevailing processes like climate mainly temperature and rainfall.

Wheat is a Rabi (winter) season crop in India. It is cultivated from sea level upto even 3000 meters of altitude. It requires about 14° C to 15° C optimum average temperature at the time of ripening. 25 cm to 75 cm of rainfall is favourable for proper growth of this crop. Soils with a clay loam having moderate water holding capacity are ideal for wheat cultivation.
Western disturbance that bring sudden winter rain in North western parts of Indian Subcontinent is very useful for growth of Wheat crop. An average of four to five western disturbances form during the winter season. Precipitation during the winter season has great importance in agriculture, particularly for rabi crops. Wheat among them is one of the most important crops, which helps to meet India's food security.
